Definitions

  • the invention relates to a transmission brake with a housing, with at least one with respect to the housing rotatably disposed friction body and at least one further attached to a braked gear shaft friction body and with an actuating device by which an actuating element against these friction body is axially pressed.
  • Such a transmission brake is for example from the DE 196 52 916 A1 known. With this can be used in an automated gearbox in countershaft design a countershaft with the mounted gears useful in their speed then slow down when reducing the speed of the drive gear of the higher gear is necessary in a upshift to speed synchronization.
  • this known transmission brake has opposing brake disks, which are arranged on the projecting into the housing of the transmission brake end of a countershaft or on the Geretebremsengephase described.
  • a fluid-actuated piston-cylinder arrangement is formed in the housing of the transmission brake, with the piston, the brake discs are pressed against each other.
  • this known transmission brake is designed to be very advantageous in itself, it still requires a hydraulic or pneumatic system that supplies the cylinder of the piston-cylinder assembly with the necessary for the brake actuation operating pressure. This is not true then disadvantageous if in the vehicle except the transmission brake also other vehicle components are present, which must be supplied with a hydraulic or pneumatic actuation or control pressure. But since there are also vehicles in which the transmission brake is the only device that requires a hydraulic or pneumatic actuation or control pressure, their installation in such a vehicle means a significant cost factor.
  • a fundamental disadvantage of fluidically actuated transmission brakes in piston-cylinder arrangements is that they require comparatively much installation space for their additional drive components (eg solenoid valves) in a vehicle area in which it is often already very cramped anyway.
  • the object of the invention is to present a transmission brake that can be actuated without a pneumatic or hydraulic pressure system and also does not require a large amount of space.
  • the friction body can be pressed by an actuating element to each other, which is axially movable by an electromagnetic actuator.
  • the actuating device has an electromagnetically effective annular coil, which is supplied with a coil current controlled by a Gerete facedungs- and -regelungs worn.
  • a plurality of individual coils in the housing of the transmission brake may preferably be arranged annular instead of a ring coil.
  • this transmission brake is fully or at least partially integrated in the wall of the transmission housing.
  • the friction body are at least partially disposed in an opening of those transmission housing wall in which protrudes the countershaft braked.
  • the toroidal coil can be fastened in a cover acting as a housing for the transmission brake, which in turn is connected to the transmission housing via fastening means.
  • the lid can also serve to cover other attached to the transmission housing wall controls.
  • this housing is preferably made of a metallic material.
  • the friction body can be provided that they are designed as brake plates and rotatably mounted on the gear shaft to be braked or on the gear housing and axially movable.
  • a phenomenonsteckveriereung is formed on the projecting into the housing of the transmission brake end of the countershaft, while the opening of the gear housing is provided with an internal spline.
  • the surface is corrugated, preferably wavy sinusoidal.
  • this has in the first variant (version B) of the invention via an armature associated with the armature, which is arranged axially movable on the splines of the transmission shaft. It is considered advantageous in this context to arrange on the gear shaft a preferably disc-shaped ring armature, which is axially movable from the coil for compressing the brake plates.
  • ring anchor is arranged axially 29iebar and non-rotatably in those splines of the gear housing wall.
  • a mounting washer or on the countershaft a radial web can be arranged, which allows a one-sided axial fixation of the ring armature or at least supported.
  • the transmission brake 1 extends to a part of its axial length in an opening of a transmission housing 2.
  • this transmission brake 1 projects beyond a transmission shaft 3, which has an external spline 10 in the region of the transmission housing wall 2.
  • a transmission shaft 3 which has an external spline 10 in the region of the transmission housing wall 2.
  • friction body 4 On this spline 10 radially outwardly pointing and spaced friction body 4 are rotatably and axially displaceable attached.
  • radially inwardly facing friction body 5 engage radially inwardly facing friction body 5, which are rotatably disposed on the edge of said gear housing opening on an internal spline 11 and axially displaceable.
  • the friction bodies 4, 5 are preferably formed as brake plates.
  • a half-shell formed housing 13 of the transmission brake 1 is arranged, which is connected via here only indicated fastening means 15 with the gear housing wall 2.
  • an electromagnetic effective toroidal coil 6, 7 is arranged, in the energization of a ring armature 8 an axially acting magnetic force is exerted.
  • the ring anchor 8 is plugged either on the external splines 10 of the transmission shaft 3 (version B) or on the internal splines 11 of the gear housing 2 (version A), so that the ring armature 8 by the magnetic force according to the arrow 9 axially against the brake plates 4, 5 of Transmission brake 1 can be pressed.
  • the axial movement 9 of the ring armature 8 to the coil 6, 7 then has an end when all the brake plates 4, 5 are pressed against a contact surface 14 on the housing 13 of the transmission brake 1.
  • a fixing plate 12 which is attached to the inside of the transmission housing 2 or as a radially aligned web 28 on the transmission shaft 3, however, limits the axial movement of the ring armature 8 in the direction of the interior of the transmission housing. 2
  • the figure also shows that the coil 6, 7 is connected via electrical lines 19, 20 to a voltage source.
  • One of the transmission brake 1 associated control and regulating device 16 controls the power supply of the coil 6, 7 in dependence on the speed of the braked transmission shaft 3.
  • this speed for example by means of a gear 23 on the transmission shaft 3 and a speed sensor 22nd can be determined, the measured values are provided via a signal line 21 of the control and regulation device 16.
  • this controller 16 outputs a control signal via a control line 17 in the form of a pulse width modulated voltage to a driver stage 18, with which the power supply to the coil 6, 7 is controlled can.
  • This embodiment illustrates that a transmission brake can be realized without hydraulic or pneumatic actuator.
  • the integration of essential components of the transmission brake in the transmission housing wall also allows a very compact design.
  • the inventive electromagnetic transmission brake 1 allows a very good controllability of the countershaft speed, while with the previously known fluid-actuated transmission brakes on the control of a solenoid valve of a piston-cylinder arrangement, the desired countershaft speed is only roughly controllable.
  • a control current can be adjusted in the toroidal coil 6, 7 of the transmission brake 1 according to the invention, which is proportional to the braking force generated by the transmission brake.
  • This speed control of the countershaft 3 can thus be relatively easily established a scheme for the entire synchronization process at a gear change.
  • variable transmission brake The advantages of such a variable transmission brake are obvious.
  • a variable brake gradient can be set with which the Improve synchronization process at a gear change.
  • transmission brake and switching operations are better controllable per se than before.
  • this controllable transmission brake 1 can react directly to changing coefficients of friction of their friction elements 4, 5 and thereby take into account, for example, wear or overheating phenomena.
  • the controllable electromagnetic transmission brake 1 can also be used as a vibration damper in the drive train. The transmission brake 1 is always operated briefly when a disturbing increase in a vibration amplitude in the drive train is sensed. In this way, with a corresponding interpretation of the transmission brake can be dispensed with a separate dual mass flywheel.
  • the transmission brake according to the invention has the further advantage that due to their controllability can also be a compensation of the friction element temperature.
  • This temperature compensation is preferably already part of the stored in the control and regulating device control and regulation program.
  • Another aspect of the invention relates to the controllable braking force of the transmission brake, so that it can be used for different gear without major structural changes. Necessary adjustments are usually limited to a change in the control and regulation software in the control and regulation device and possibly to a change in the number of brake discs.
  • the brake discs are formed so that their surface is corrugated, preferably corrugated sinusoidally in the circumferential direction.
